Simulation of On-Board Diagnostics in Automobiles Using CAN Protocol

More than 70 ECUs are implemented in cars, and the number is still increasing. As a result, the complexity of automotive networks and cabling is extensive. In order to reduce the amount of wiring and diagnose wiring faults, the CAN bus may be used in vehicles to connect different ECUs. This paper is to simulate a working hardware model of a vehicle monitoring system indicating temperature and fuel status via CAN protocol. The communication between two nodes i.e. the transmitter and the receiver is via CAN protocol.
